Is there a way to create a BRR svrepdesign from a survey design when the number of PSUs is odd in one or more stratum? Creating a JKn svrepdesign with that condition works okay, but when I tried to create a svrepdesign with type="BRR" I get an error and this message: "Can't split with odd numbers of PSUs in a stratum" I get that message when I tell it to merge the PSUs. Maybe I'm just not do...

Version 1.9 of the survey package, now percolating through CRAN, adds a beta implementation of replication weights. These can either be created from a survey design (using BRR, JK1, or JKn schemes) or provided by the user.

As with earlier versions of the package, I particularly welcome feedback on the user interface from practising survey statisticians....

Hi all I'm running a Win32 application, Ecco Pro, under Wine on my Gentoo Linux system. The app is 'mostly working' but there are some circumstances where it repeatably crashes. I'd like to investigate further to see if I can improve things. I have an embedded systems & windows programming background, so I'm confident I have some of the skills; however I'm a novice

Hi, I''m having what I believe to be a typecast problem with ActiveRecord and Associations. In the code below, I need to flag a contact record for deletion if the contact doesn''t have any addresses or books records: sql = "select id, delete_flag from contacts where id = #{params[:id]}" contact = Contact.find_by_sql(sql) if (contact[0].addresses.count +
